Abstract (en)
A lockable safety shield (42) for a prefillable syringe (10) is provided. The design of the lockable safety shield enhances pharmaceutical manufacturers' ease of assembling the various components as part of its filling or processing of the prefillable syringes in normal practice. A collar (32) is attachable to the distal hub (24) of the prefillable syringe. A safety shield (42) is axially slidable over the collar (32) between a retracted position, wherein the distal end (28) of the piercing element (26) associated with the prefillable syringe (10) is exposed, and an extended position, wherein the safety shield (42) is locked to the collar (32) to protectively cover the distal end (28) of the piercing element (26). The safety shield (42) includes locking structure configured so that the shield, as supplied to the pharmaceutical manufacturer, can be easily fitted to the syringe (10). The locking structure includes at least one deflectable arm (50) provided on the body of the shield (42). The deflectable arm includes a proximal end (52) deflectable towards the interior of the shield. A stop member (70) is provided on the interior of a shield in spaced relation to the proximal end (52) of the deflectable arm (50). A ring (80) is axially slidable over the shield to deflect the arm (50) towards the interior of the shield (42) to activate the locking structure. The safety shield (42) is slid distally by an end user such that the collar (32) is lockingly retained between the stop member (70) and the proximal end (52) of the deflectable arm (50). The collar (32), the stop member (70) and the deflectable arm (50) may be configured to provide tactile as well as audible indication of locking to the end user.
